Confluent Control Center stops working after a couple of hours

Hello everybody.

This issue I am getting with Control Center is making me go insane. After I deploy Confluent’s Control Center using CRDs provided from Confluent for Kubernetes Operator, it works fine for a couple of hours. And then the next day, it starts crashing over and over, and throwing the below error. I checked everywhere on the Internet. I tried every possible configuration, and yet I was not able to fix it. Any help is much appreciated.

Aziz:~/environment $ kubectl logs controlcenter-0 | grep ERROR
